A method for determining the column curve from tests of columns with equal restraints against rotation on the ends

A method for determining the column curve from tests of columns with equal restraints against rotation on the ends

Date: August 1, 1943
Creator: Lundquist, Eugene E; Rossman, Carl A & Houbolt, John C
Description: The results are presented of a theoretical study for the determination of the column curve from tests of column specimens having ends equally restrained against rotation. The theory of this problem is studied and a curve is shown relating the fixity coefficient c to the critical load, the length of the column, and the magnitude of the elastic restraint. A method of using this curve for the determination of the column curve for columns with pin ends from tests of columns with elastically restrained ends is presented. The results of the method as applied to a series of tests on thin-strip columns of stainless steel are also given.

Torsion of flanged members with cross sections restrained against warping

Torsion of flanged members with cross sections restrained against warping

Date: March 1, 1943
Creator: Hill, H N
Description: The longitudinal stresses and the stiffness of flange members - I-beams, channels, and Z-bars - were investigated when these members were subjected to torque with constraint against cross-sectional warping. Measured angles of rotation agreed with corresponding calculated values in which the torsion bending factor of the cross section was involved; the agreement was better for the I-beam and the Z-bar than for the channel. Longitudinal stresses measured at the mid-span were found to agree with the calculated values that involved unit warping as well as the torsion-bending factors: the channel showed the greatest discrepancy between measured and calculated values. When commonly given expressions for rotations and maximum longitudinal stresses in a twisted I-beam were applied to the channel and to the Z-bar, values were obtained that were in reasonably good agreement with values obtained by the method of torsion-bending constant and unit warping.

Round heat-treated chromium-molybdenum-steel tubing under combined loads

Round heat-treated chromium-molybdenum-steel tubing under combined loads

Date: July 1, 1943
Creator: Osgood, William R
Description: The results of tests of round heat-treated chromium-molybdenum-steel tubing are presented. Tests were made on tubing under axial load, bending load, torsional load, combined bending and axial load, combined bending and torsional load, and combined axial, bending, and torsional load. Tensile and compressive tests were made to determine the properties of the material. Formulas are given for the evaluation of the maximum strength of this steel tubing under individual or combined loads. The solution of an example is included to show the procedure to be followed in designing a tubular cantilever member to carry combined loads.

Some investigations of the general instability of stiffened metal cylinders VII : stiffened metal cylinders subjected to combined bending and torsion

Some investigations of the general instability of stiffened metal cylinders VII : stiffened metal cylinders subjected to combined bending and torsion

Date: November 1, 1943
Creator: unknown
Description: This report summarizes the work that has been carried on in the experimental investigation of the problem of the general instability of stiffened metal cylinders subjected to combined bending and torsion at the C.I.T. This part of the investigation included tests on 26 sheet-covered specimens. An interaction curve for the case of combined bending and torsion is presented. The results of tests of 17 specimens subjected to pure torsion are also given.
